Install a stove using external Twinwall Insulated pipe
This type of installation is very popular as many of our customers do not want to see any or very little stove pipe within the room. If you wish to use the system pictured left, then you must note that you must come off the back of the stove at 45 degrees!
Once your stove is in position you must decide whether you would like to use a single skin stove pipe to come out of the top of the stove, or if you would like to use Twinwall insulated pipe all the way.
If you want to use a matt black single skin pipe directly out of the top of the stove then you must ensure that the stove pipe is a distance of at least 3 times its diameter away from any combustible materials (For example if your using a 5" flue it would need to be at least 15" away from a combustible)- If you are using a Twinwall pipe then it would only need to be at least 2" (50mm) away from any combustible materials.
If you do decide to use a single skin pipe first then you must ensure that the double insulated pipe comes into the room by at least 6" (150mm), In other words the single skin pipe must stop at least 6"-7" below the ceiling.
If you however decide to use double insulated all the way then you would use the Twinwall Adapter in the stove and run the double skin pipe all the way.
It is required that you use a support bracket at least every 2 meters to provide adequate support to the pipe.
